boy helpppo

I'm a senior in high school and I go to a pretty small school of 160 students. I have a guy friend who is really popular and kinda the star of the bball team and I have big crush on him. He has a girlfriend in freshmen year of college in another state and idk what to do. Wait for them to break up eventually, ever be honest about my feelings or what? My friend says he probably knows a little bit that I'm into him. I just don't know what to do. 😩😬
